Abstract: MIXING FLUFFY AND RIGID PLASTICS             MATERIALS          ABSTRACT OF THE DISCLOSURE        Apparatus and methods for mixing fluffy scrap and rigid plastics materials for subsequent discharge of the mixture to an extruder comprises an upright mixing chamber to which rigid, fluent plastics pellets are fed by gravity and into which fluffy, ground scrap plastics material is fed by positive drive means from a hopper.  Delivery of an adequate quantity of scrap material to the mixing chamber is assured by the provision in the scrap hopper of an agita-ting mechanism which is interposed between the top and the bottom of the hopper and which is operable to permit scrap material to pass downwardly to the bottom of the hopper for engagement by a feeding auger, but which prevents subjecting such scrap material to the weight of additional scrap in the hopper, thereby preventing bridging of the scrap at the lower end of the hopper.  Feeding of the base and scrap ma-terials from the mixing chamber to the extruder is achieved by a rotary auger having an interrupted vane which provides for alternate compaction and expansion of the scrap material with consequent  facilitation of the entry of base material to the mixing chamber.

Abstract: ABSTRACT OF THE DISCLOSURE                A process and associated apparatus are provided for producing cold flow formed items from slugs.          First and second dies are aligned for relative movement axially towards and away from one another.  The dies have respective opposed first and second faces and the first face defines a cavity having portions including generally axial walls.  The first die has a peripheral chamfer extend-ing axially away from the first face and a sleeve is provided containing the dies to combine with outer parts of the second face and the peripheral chamfer to define an annular space.  The slug is formed into the item by causing relative movement between the dies to impact the slug and then causing further relative movement so that the slug is caused to flow into contact with the axial walls and also into the annular space so that destructive forces applied to the axial walls are countered by forces applied to the chamfer thereby stabilizing the material of the first die between the axial walls and the chamfer.  A slug for use with the die set is also provided.

Abstract: Docket RWH-1 "Bottle Carrier"            ABSTRACT OF THE DISCLOSURE A one-piece, integrally molded plastic carrier adapted for supporting a plurality of bottles (such as beverage bottles) in a space envelope which is essentially the same as that space previously utilized by cardboard cartons. In an embodiment for carry-ing six bottles, a pair of non-planar handle supports extend upwardly from the base, with each of the supports resting in the central space between groupings of four bot-ties that are arranged to form a "square". The handle supports may be generally cylindrical or T-shaped, or a combination thereof; but in any case they are non-planar. The moment of inertia of the handle supports is high, so that the stiffness of the carrier is correspondingly high. A substantial slot is provided in the base between the two handle supports, and the slot is sized so that two bottle carriers may be nested to-gether--with the handle of one carrier passing through the slot and into the bottom of another carrier. The structural elements of the carrier are appropriately sized and tapered (where necessary) in order to permit straight-pull injection molding.

Abstract: ELECTRONIC BOTTLE INSPECTOR HAVING PARTICLE       AND LIQUID DETECTION CAPABILITIES                              ABSTRACT          This invention relates to equipment for auto-matically detecting the presence of certain liquids and foreign objects in containers.  Prior art bottle inspec-tion systems utilize an incandescent light source to provide an image of the bottom of the bottle, with a scanner or sensor array for sensing different portions of the image.  Such systems merely determine relative light and dark areas and are effective only in detecting the presence of opaque objects. The disadvantages of the prior art are overcome in the present invention by means of an electronic bottle inspector having particle and liquid detection capabilities through the use of sensing systems in the visible and infra-red light range. Light from an incandescent source presents an image of the bottom of the bottle on a rotating scanner having a generally non-reflective background and one or more reflecting segments which scan the image focused thereon, with at least the reflective segments being contoured so the light falling thereon from the respective portion of the bottle bottom image is focused onto a detector. Particulate matter creates a dip in detector output.  For liquid detection infra-red radiation passing through holes in the scanner is filtered to allow peaking of an infra-red detector around one of the absorption bands of the liquid and a corresponding drop in the AC coupled amplitude of the detector.

Abstract: ENERGY UTILIZATION OR CONSUMPTION RECORDING METHOD AND ARRANGEMENT                            Abstract Of The Disclosure Energy utilized or consumed at a given location or facility causes pulses to be generated as a function of the instant rate of energy use, and such pulses are counted at succeeding discrete time intervals.          The succeeding interval summation count values are recorded in digital form at respective discrete locations in a memory, particularly on an ultraviolet (UV) light-erasable PROM (EPROM) contained in a removable cartridge having a UV substantially opaque case.  The interval summation count values are summed to provide a grand total energy or power utilization or consumption figure which is fed into and stored at a discrete location in the EPROM memory at the end of the recording period.  The succeeding interval counts are successively compared and the peak count value for that interval having the greatest energy usage within a particular total time period composed of a multiple of such succeeding discrete time intervals is recorded on the EPROM at the conclusion of the particular total time period and the cartridge is removed, after having also recorded on the EPROM in digital data form and at respective discrete memory locations the respective times of beginning and end of the particular total time period of energy use measurement and recording, as well as recording thereon the place or location of the energy use facility whose energy use is being measured and recorded.
